  78 /*  [Description]
  79
  80     With this method, can the SfxViewFrame be forced to immediately provide
  81     the new title from the <SfxObjectShell>.
  82
  83     [Note]
  84
  85     This is for example necessary if one listens to the SfxObjectShell as
  86     SfxListener and then react on the <SfxSimpleHint> SfxHintId::TitleChanged,
  87     then query the title of his views. However these views (SfxTopViewFrames)
  88     are  also SfxListener and because the order of notifications might not be
  89     fixed, the title update will be enforced in advance.
